This is a marvelous read, even for grown-ups.
Also, check out the link to the free audio book from Librivox, read by Karen Savage. She tells the story at a a cracking pace.
Full of novel ideas. The book is slightly overlong - the last section being a bit tedious, and some of the relationships between characters made it seem like a hi-tech soap opera at times. Apart from those very slight blemishes, it's definitely a Must Read for science fiction fans.
Overall, I'd give it 4.75 out of 5.
btw, there's an explanation of Accelerando's technical terms at wikibooks.org
Although this science fiction novel was written in the 1950s, it is still very readable, today. Andre Norton concentrates on her characters (but there's plenty of action to drive it along) which means that the technology here, as imagined in the 1950s, doesn't date it too much.
This adventure, pigeon-holed as a juvenile's novel by some, takes place on a world where a new survey ship has arrived from Earth. Down below, is a war-devastated civilisation. The races that co-exist outside the few remaining populated cities have developed telepathy - including some humans from a long ago colony ship - and can communicate with some species of wild animals - which comes in useful as the story evolves.
As in most good science fiction stories, what follows is a stuggle that will decide the future of the entire planet.
